Definitions

  • the present invention relates to drilling equipment, and more particularly, to an apparatus for changing drill rods within a drill string of a drilling rig.
  • drilling equipment is normally provided with operator cabs to separate the operator from the noise and dust of the drilling operations.
  • Most drilling operations further require that drill extension rods be added to a drill string in order to enable the drill bit to reach a required drilling depth.
  • drill extension rods be added to a drill string in order to enable the drill bit to reach a required drilling depth.
  • an operator is within a cab, he is unable to manually add drill rods to the drill string.
  • the drill rod is too heavy for the operator to lift manually.
  • One type of presently existing automated rod changing system utilizes a separate rotating system to unthread the drill rod and coupling from adjacent drill rods in the drill string. These types of systems require a great deal of additional hardware causing the system to be very expensive.
  • Other rod changing systems utilize the rotating system of a percussive drill to unthread the drill rod and coupling from the drill string. With these type of rod changing systems, the drill rod must be securely held while the percussive drill threaded element is threaded into the upper coupling ⁇ n the drill rod. This operation enables the upper coupling, drill rod and percussive drill threaded element to rotate as a single element and unthreaded from the lower coupling when a drill rod is removed from the drill string.
  • the upper coupling After unthreading from the lower coupling, the upper coupling must be loosened from the percussive drill threaded element so that the drill rod and upper coupling can be moved to a storage area.
  • Current designs in the industry use a separate break-out wrench to grip the upper coupling while the percussive drill threaded element is threaded or unthreaded from the coupling.
  • the separate break-out wrench is mounted on the drill mast, feed-column, or the percussive drill mounting plate. In all of these cases, the extra break-out wrench assembly is expensive and requires additional maintenance for the drilling machine.
  • the drill rod changing system comprises upper and lower support arms connected to the drill feed and extending outward therefrom.
  • a lifting apparatus enabling drill rods to be lifted between lowered and raised positions.
  • the lifting assembly includes an upper gripping assembly for gripping the drill rod around the upper coupling of the drill rod.
  • a lower gripping assembly grips the lower portion of the drill rod
  • FIGURE 1 is a front view of the rod changing system of the present invention
  • FIGURE 2 is a side view of the upper gripper assembly and the lifting mechanism
  • FIGURE 3 is a top view of the upper gripper assembly
  • FIGURE 4 is a side view of the lower gripper assembly
  • FIGURE 5 is a top view of the lower transfer assembly
  • FIGURE 6 is a top view of the support assembly.
  • FIGURE 1 there is illustrated a front view of the rod changing system of the present invention.
  • the rod changing system 1 0 is connected to the drill mast 1 2 via the upper rod support assembly 1 4 and lower rod support assembly 1 6.
  • the upper rod support assembly 1 4 and lower rod support assembly 1 6 assist in guiding and supporting a drill rod 24 to storage rack 28.
  • the transfer assembly 1 8 is mounted to the upper and lower rod support assemblies and consists of the upper gripper assembly 20, lower gripper assembly 22, and lifting mechanism 24.
  • a rotator assembly 41 consists of upper drive shaft 42 connected to lower drive shaft 46 via a universal joint 48.
  • the lower drive shaft 46 further connects by a universal joint 52 to a motor assembly 50 mounted on lower support arm 1 6.
  • the motor assembly 50 preferably comprises a rack and pinion rotator but may comprise any means suitable for rotating the upper and lower drive shafts 42, 48.
  • the motor assembly 50 rotates the upper and lower drive shafts 42, 48 causing the gripper assemblies 20,22 to rotate in an arcuate path and move a gripped drill rod 26 from a position adjacent the drill string to a storage position.
  • the upper gripper assembly 20 consists of a pair of opposed jaws 30 pivotally connected to the upper mounting bracket 40 for gripping the upper coupling 32 of the drill rod 26. When closed, the jaws 30 provide a seat 34 for retaining the bottom edge 36 of upper coupling 32. This allows the upper gripper assembly 20 to retain the drill rod 26 and upper coupling 32 when clamped.
  • Each jaw 30 is actuated by a hydraulic actuator 38 connecting the jaw 30 to the upper mounting bracket 40.
  • the hydraulic actuator 38 actuates the jaws to a gripping position for tightly holding the upper coupling and drill rod to prevent their rotation during unthreading/threading procedures and to a support position for holding the upper coupling 32 to enable lifting of the drill rods 26 but still allowing rotation of the upper coupling and drill rod within the upper gripper assembly 20.
  • Upper mounting bracket 40 is connected to upper drive shaft 42 such that the bracket may slide up and down the shaft. Movement of the bracket 40 and upper gripper assembly 20 is enabled by hydraulic lift actuator 44.
  • the lift actuator 44 couples the upper drive shaft 42 to the upper mounting bracket 40.
  • Lift actuator 44 enables the upper gripper assembly 20 to be moved from a lowered position located generally at 36 to a raised position as shown in FIGURE 3 by raising or lowering the upper mounting bracket 40. This allows a drill rod 26 to be raised and lowered as required.
  • the lower gripper assembly 22 comprises a pair of opposed jaws 60 for clamping around the lower portion of a drill rod 26.
  • the jaws 60 are pivotally connected to a lower mounting bracket 62 which is connected to the lower drive shaft 46.
  • the jaws 60 are actuated by hydraulic actuators 64 connected to the jaws and the lower mounting bracket 62.
  • the hydraulic actuators 64 actuate the jaws to a gripping position for tightly holding the drill rod 26 to prevent rotation of the drill rod and to a support position to support the drill rod but still enable rotation of the drill rod within the lower gripper assembly 22.
  • FIGURE 6 there is illustrated a top view of an upper or lower support assembly 70.
  • the support assembly 70 provides a slot 72 for containing a plurality of drill rods 26 that are being loaded into or removed from the drill string.
  • the support assembly 70 spaces the drill rods 26 apart and retains them in a stable position.
  • the drill rods 26 are spaced apart and held in place by a spacing mechanism 76.
  • the spacing mechanism 76 comprises a spring-loaded piston 78 and rocker arm 80.
  • the rocker arm 80 separates the drill rods 26 and maintains them in a storage position. Oversized mounting holes and shims allow the support assemblies to hold various size drill rods such as 38 millimeter, 45 millimeter or 51 millimeter drill rods.
  • a drill rod 26 within the storage rack 28 is gripped by actuating the jaws of the upper and lower gripper assemblies 20, 22 to the gripping position.
  • the lifting mechanism 24 is actuated to lift the drill rod 26 to the raised position.
  • the rotation assembly 41 swings the drill rod 26 into position under the threaded striking bar 90 of the drill head 92 such that the drill rod is coaxial with the drill string.
  • the drill rod 26 is lowered by the lifting mechanism 24 into the upper coupling of a drill rod 94 at the top of the drill string held by the centralizer 96.
  • the threaded striking bar 90 is threaded into the upper coupling of the drill rod.
  • the gripping assemblies are then actuated to the holding position, and the drill rod 26 is threaded onto the upper coupling of the adjacent drill rod 94 located in the centralizer by the striking bar 90.
  • the lifting mechanism 1 8 lowers the drill rod 26 as the rod is threaded into the upper coupling of the adjacent drill rod 94.
  • the gripper assemblies 20, 22 of the rod changer When removing a drill rod 26 from the drill string, the gripper assemblies 20, 22 of the rod changer are positioned about a drill rod with the upper gripper assembly 20 supporting the upper coupling of the drill rod and the lower gripper assembly 22 supporting the lower portion of the drill rod.
  • the opposed jaws 30 of the gripping assemblies 20, 22 are actuated to the gripping position on the drill rod 26 so that the threaded striking bar 90 may be threaded into the upper coupling.
  • the opposed jaws 30 are then relaxed to the support position to enable rotation of the drill rod 26 while the drill rod is unthreaded from the coupling of the drill rod 94 locked in the centralizer 96.
  • the lifting mechanism 24 of the rod changer enables the drill rod 26 to follow the upper coupling upward as the drill rod threads out of the coupling of the drill rod 94 locked in the centralizer 96.
  • the opposed jaws 30 of the gripper assemblies 20, 22 are again actuated to a gripping position to enable the threaded striking bar 90 to be unthreaded from the upper coupling of the drill rod 26.
  • the rotator assembly 41 is then actuated to position the drill rod 26 over the storage rack 28 and lift mechanism 1 8 is actuated to lower the drill rod into the storage rack 28.
